Antietam National Battlefield is seen in Sharpsburg, Md., on Nov. 5, 2011. The battle of Antietam was one of five Civil War battlefields that in the 1890s came under the administration of the War Department as a park. Almost a century later, the prospect of encroaching development led to a series of public-private partnerships that today extend preservation beyond the battlefield to the surrounding viewscape. Those efforts allow visitors to maintain a strong sense of what Antietam felt like on September 17, 1862, when well over 100,000 soldiers fought at relatively close range in a stalemate that gave President Lincoln enough of a Union victory to issue his Emancipation Proclamation.

The Nature Conservancy hosts a group of roughly 30 visitors for a vernal pool hike at Forest Pools Preserve, adjacent to Kings Gap State Park in Cumberland County, Pa., on March 25, 2016. Because vernal pools, or seasonal wetlands, dry up every year, they don't harbor fish and thus are critical habitat for many amphibian species. (Photo by Will Parson/Chesapeake Bay Program).
